TL;DR: Density functional theory calculation results indicate that the inherent electronic properties of SLG and CFGG such as the linear Dirac band and half-metallic band structure are preserved in the vicinity of the interface, suggesting that the SLG/CFGG heterostructure possesses distinctive advantages over other reported graphene/ferromagnet heterostructures for realizing effective transport of highly spin-polarized electrons in graphene-based vertical SV and other advanced spintronic devices.
